[strongSwan] ipsec doesn't honor environment variables

None of the programs called by the ipsec script (starter, stroke, etc.)
currently use any of these environment variables, instead the paths are
determined at compile time.  So changing the variables would have no
effect at all.  I guess that was some FreeS/WAN thing that never really
applied to strongSwan.

So while the variables are not used they are still provided to the
called programs.  I changed the manual page to that effect with [1].
